Electrical connector

Abstract

An electrical connector includes an insulating housing (100) consisting of a front section (111) and a rear section (112), the front section having a cylindrical contact support section (120) with a plurality of contact apertures (121) extending along its longitudinal axis and the rear section having a rear cavity (119) in a lower portion thereof; a plurality of L-shaped contact elements (300) each having a contact portion (301), an intermediate portion (302) extending rearwardly from the contact portion, and a terminal portion (303) extending downwardly from the intermediate portion, the contact portion being fitted into the contact aperture; and a block member (200) having a plurality of lateral channels (201) for receiving the intermediate portions and a plurality of vatical apertures (202) for receiving the terminal portions, the block member being fitted into the rear cavity so that the intermediate and terminal portions are fitted into the lateral channels and the vertical apertures respectively.

We claim: 
     
       1. An electrical connector comprising an insulating housing, a metal hood member, and a plurality of contact elements mounted within said insulating housing, characterized in that said contact elements have a contact portion for contact with a mating contact element within said insulating housing, an intermediate portion extending rearwardly from said contact portion, and a terminal portion extending downwardly from said intermediate portion through said insulating housing;   said insulating housing has an annular recess for receiving a mating shell member, a rear cavity for receiving a block member for supporting said intermediate portions of contact elements within said hood member;   said hood member has a pair of leg members to be connected to a ground circuit on a printed circuit board and a pair of flanges extending inwardly from lower edges thereof for supporting said block member; and that   said block member has lateral channels for receiving said intermediate portions of contact elements and vertical apertures through which said terminal portions of contact elements are pass.   
     
     
       2. An electrical connector comprising: an insulating housing consisting of a front section and a rear section said front section having a cylindrical contact support portion with a plurality of contact apertures extending along its longitudinal axis and said rear section having attachment slots in a lower portion thereof and a U-shaped recess in an upper portion thereof;   a plurality of L-shaped contact elements each having a contact portion fitted into said contact aperture, an intermediate portion extending rearwardly from said contact portion, and a terminal portion extending downwardly from said intermediate portion;   a block member having a plurality of lateral channels for receiving said intermediate portions and a plurality of vertical apertures for receiving said terminal portions, said block member being fitted into a rear cavity so that said intermediate and terminal portions are fitted into said lateral channels and said vertical apertures respectively; and   a metal hood member having a U-shaped link section fitted into said U-shaped recess of said insulation housing, a pair of elongated contacts extending forwardly from an upper portion of said link section for contact with a mating connector plug; and a pair of attachment portions extending forwardly from a lower portion of said link section and having a downwardly extending leg for contact with a ground of a printed circuit board.   
     
     
       3. The electrical connector of claim 2, wherein said hood member has a pair of flanges extending inwardly from a lower edge of said attachment section and said block member has a pair of stepped lower edges such that when said hood member is joined to said insulating housing, said flanges engage said lower edges to support said block member. 
     
     
       4. The electrical connector of claim 2, wherein said metal hood member has a back plate for covering an entire back side of said block member so as to enhance its shielding effects. 
     
     
       5. An electrical connector comprising: an insulating housing consisting of a front section and a rear section, said front section having an annular recess extending rearwardly from a front face of said front section, at least one radial seat radially extending from said annular recess on said front face, and a pair of T-shaped latch slots extending rearwardly from a lower portion of said front face and said rear section having a pair of attachment slots extending forwardly from a lower end portion of said rear section to communicate with said T-shaped latch slots;   a cylindrical shield member fitted in said annular recess and having at least one contact lug resting on said radial seat;   an end face protection member having a pair of latch lances with a U-shaped contact, which extend rearwardly from a lower portion thereof and fitted into said T-shaped latch slots for securing said end face protection member to said insulating housing such that said contact lug is brought into contact with said end face protection member; and   a metal hood member having a U-shaped link section and a pair of attachment sections extending forwardly from a lower portion of said link section and having a contact portion at its free end such that when said attachment sections are fitted into said attachment slots, said contact portions are brought into contact with said U-shaped contacts of said end face protection member, thereby completing electrical continuity from said cylindrical shield member to said end face protection member to said hood member.
